My first 2-channel amp - Please comment

I don't think the cathode follower is a detriment at all. It's just a different sound and the cathode follower helps to drive the tone stack harder. You'll notice in the KOC design the tone stack slope resistor is 100k- this is probably a good idea since it makes it easier for the triode plate to drive the tone stack. It makes the tone stack higher loss and weights it toward brighter/more treble. The cathode follower creates a tonal difference by drawing grid current on larger signals. The jury is out as to what sounds better- it's really a personal preference.

I was only assuming you wanted things simpler. If you don't mind the higher parts count you could build the Bogner design as found on the web. The layout is likely to be mildly complex but if you've built a few single channel amps it shouldn't be bad.

I'm just a fan of my simpler design because it allows you to use just 2 triodes and a high voltage mosfet to achieve a decent clean and dirty channel and a pedal-friendly effect loop. I have not built it yet so I don't know if it works correctly but there is really no reason why it shouldn't. If you'd like I can draw it up for you.

Oops, I meant to change the stack back to the one with 100k slope - I understand the relationship to the driving source.

I do prefer a simpler design, which is why I excluded a loop at the onset. I'd hate to regret not including one though, for a reverb pedal, delay, etc, so I may do some more research...

Thanks again.
